    The Samsung S21 Ultra appears to be fine in the two weeks since we received it and was as promised. Ordering was easy and delivery was as expected. Our trade-in offer was much lower than we had anticipated ($25.00) for a phone in complete working order without problems. I have previously purchased certified, refurbished smartphones directly from Samsung and felt we received a much better & fairer trade-in offer. While the price of the S21 Ultra was cheaper from Back Market, I believe that I might have fared better buying from Samsung in terms of overall cost. I will research more closely when it's time for our next purchase.

    The phone is amazing and just as I expected. It did have a small scratch on the front that is deep enough to see when the phone isn't on when I ordered the excellent version, but other than that it's great!! I would definitely recommend it to anyone looking to buy refurbished!

    Trading in my beat-up S21Ultra with damaged screen for this excellent condition replacement enabled me to, in turn, take advantage of trade-in promotion at Samsung Store. My old phone was worthless for trade-in otherwise. The refurbisher who purchased my trade-in tried to claim that it didn't take a charge... but with my photos in hand, the Backmarket staff swiftly dealt with that. Be sure to take photos of live phone, and of each stage of packaging, so that Backmarket is able to support you in case of dispute. Great customer service!

    Delivery wason time and the phone arrived as described (S21 Ultra in good condition). Everything works fine, except the battery which lasts only half a day under little to moderate useage. From the descriptions of this model, I expected a full day of heavy useage to two days of light use on a fully charged battery. I know it's a used phone, but if the battery is this weak it should have been swapped in order to consider this a refurbished phone.

    There was a scratch on the back by the camera, I give the quality of this refurbished device 4.5/5 stars. Everything else 💪 appears to be in good working order. This is a great phone for the price. The ultra that is. 12gb ram...super fast 🏃‍♂️
